No, I do not go every day to the gym, but try to exercise regularly and to keep myself fit. Preferably with exercises using your own body weight. Here I am trying to run a little muscle building. I drink usually a shake with 25g before training. Regarding the quality and ingredients of the product, I am not a professional and would therefore not make any classification. The ingredient list is itself, but attached in detail and clearly legible on the packaging. So no need to take a close look, as often unfortunately necessary. This product is Made in Germany, thus generating, in terms of pollutants some confidence in me. Since I only have a hand shaker, I tried to shake with milk and water. The powder is very easy to solve. I tasted the shake with milk very well, with water, unfortunately not. But as tastes obviously differ, everyone must decide for themselves at the end.
